Abstract: The aim of the study is to determine the possibility of sweet potato (Ipomoea batatas) addition as feed for white leg shrimp (Litopenaeus vannamei) under biofloc rearing condition. The experiment was randomly set up with four feeding treatments including (i) 100% commercial pellet without sweet potato addition (control), (ii) commercial pellet in combination with 10% sweet potato addition, (iii) 20% sweet potato addition, and (iv) 30% sweet potato addition. Shrimps (0.76±0.15 g; 4.4±0.6 cm) were cultured in biofloc system (C: N = 15: 1) at stocking density of 150 shrimp/m3 and water salinity of 15‰. After 90 days of culture, the increase sweet potato addition increased shrimp weight.
